PHP strnatcmp() Function
 Complete PHP String Reference
Definition and Usage
The strnatcmp() function compares two strings using a "natural" algorithm.
In a natural algorithm, the number 2 is less than the number 10. In
computer sorting, 10 is less than 2, because the first number in "10" is
less than 2.
This function returns:
- 0 - if the two strings are equal
- <0 - if string1 is less than string2
- >0 - if string1 is greater than string2
